Reference of 15155-41-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 15155-41-6, name is 4,7-Dibromo-2,1,3-benzothiadiazole belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
The reaction carried out by taking the suspension of compound 1 (2g, 6.8 mmol) in 25 mL absolute ethanol kept at 0 C, sodium borohydride(0.3 g, 8 mmol) was added by pinch wise and stirred at normaltemperature ffor 1 h. A pinch off cobaltous chloride was added into themixture for the successful finishing of the reaction. Finally, the productwas transferred to crushed ice followed by stirring, the obtained whiteprecipitate was filtered off and washed with deionized water. The resultantwhite residue was dehydrated under vacuum. Compound (2),yield 85%, 1H NMR spectrum (500 MHz, CDCl3) & (ppm) 6.75 (d, 2H).
The synthetic route of 4,7-Dibromo-2,1,3-benzothiadiazole has been constantly updated, and we look forward to future research findings.
